Realisticly speaking, you have multiple options with regards to passwordless or formless logins in node.js/express.js and therefore sails.js, as sails is built on top of both.

How you would approach the solution, really depends on the scale and use of your application/applications. For example; will the same login credentials be used to access multiple applications or a single web application, will the application be available only in an intranet or across the whole WWW.

Regardless of the scenario above, there will next to always be some initial setup required by the user, whether that is an initial sign up with an identity provider or an initial sign up with your application. The sign up form, will not dissappear entirely, rather it will become a one time event.

So let's look at some options and how we might introduce them into an express/sails application/s, I will start with the most basic and work down in difficulty.

Option 1: Make use of the sails session store. From your code, you have already started doing this. The logic works something like this:

Your user signs up or logs in for the first time. At this stage you set the users session to be authenticated.
